//Android webview 设置cookie

public void synCookies(Context context, String url, String cookie) {
      CookieSyncManager.createInstance(context);
      CookieManager cookieManager = CookieManager.getInstance();
      cookieManager.setAcceptCookie(true);
      cookieManager.setCookie(url, cookie);//cookies是在HttpClient中获得的cookie
      CookieSyncManager.getInstance().sync();
  }

//调用:

  synCookies(MainActivity.this, ".xxx.com", "token=" + tokenBean.getToken());
	

注意：设置cookie时，是 .caocao.com ，记住前面有个点

集成微信支付闪退：

按照以下几点来检查，
1，你签名中的key，也就是你的API密钥key，这个参数要你们自己到商户平台设置的，设置的规则是32位数字与字母大小写的组合的随机数，不能设置成签名串和参数appsecret，你们有正确设置吗？？？
2，检查开放平台对应的包名与签名是否有正确设置。
https://pay.weixin.qq.com/wiki/doc/api/app/app.php?chapter=8_5 这里有详细的设置说明。
3，调用支付使用的noncestr这个参数必须和商家服务器调用统一下单接口返回的那个noncestr一致
4， 从预支付订单返回的数据 ，没有重新签名，也会引起这个问题。 （目前我是因为后台获取到预支付id后，没有进行数据二次签名，导致闪退）
5，重新安装微信后试试。

解决方案
mac执行 ./gradlew assembleDebug --stacktrace 查看具体错误
这边遇到的问题是，依赖库中的minSdk和当前项目的不一致，解决该错误，改成一致的即可

  uses-sdk:minSdkVersion 15 cannot be smaller than version 16 declared in library [com.github.razerdp:BasePopup:2.1.9] /Users/zhaoshunchen/.gradle/caches/transforms-1/files-1.1/BasePopup-2.1.9.aar/88668d5e7816d523f8df1074f1e86b57/AndroidManifest.xml as the library might be using APIs not available in 15
        Suggestion: use a compatible library with a minSdk of at most 15,
                or increase this project's minSdk version to at least 16,
                or use tools:overrideLibrary="razerdp.library" to force usage (may lead to runtime failures)
